UNITED STATES ERNESTO ROMANO, OF NEW YORK, N. Y.

TAPE-FEEDING ATTACHMENT FOR SEWING MACHINES.

Application filed April 26, 1922. Serial No. 556,729.

To all whom it may concern:

Be it known that I, ERNESTO RoMANo, a subject of the King of Italy, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Tape-Feedin Attachments for Sewing Machines, of whlch the following is a specification.

The present invention consists of a simple and effective attachment for sewing machines for the purpose of feeding and ten. sioning tape as it is sewed to a piece of work in the ordinary sewing machine. The in-- vention comprises a cylindrical shell formed with tape slots at approximately its opposite sides and an inner slotted member adjustably mounted in said shell. The-shell is mounted upon a suitable support by which it can be moved into and out of operative position and is provided with means for engaging the presser foot of a sewing machine, so as to be held in working relation to the stitch forming mechanism of the machine. The support preferably carries a tape guide which may be made in the form of a properly shaped and bracedwire integral with the supporting arm. A. device is also provided for adjusting the inner slotted member in the cylindrical shell for the purpose of determining the tension upon the tape as it feeds through the device.

In order that my invention may be fully understood, I will first describe the same with reference to the accompanying drawing and afterwards point out the novelty more particularly in the annexed claims.

In said drawing:

Figure 1 is a front elevation of the improved tape i eeding and tensioning device inoperative relation to a sewlng machine;

Figure 2 is a sectional slde elevation of the same taken 011 the line 22 of Fig. 1;

Figure 3 is a sectional plan view of the same taken on the line 3-3 of Fig. 1;

Figure i-is a view similar to Fig. 3 showing the attachment moved back out of the way into the position assumed when it is not in use;

F'gure 5 is a detail sectional View taken on the line 55 of Fig. 3;

Figure 6 is a detail longitudinal sectional view of the feeding and tensioning members;

Figures 7 and 8 are detail cross-sectional views oi the same showing two positions of the parts. 7

Figure 9 is a detail perspective view of the tape tensioning device.

.10 is a slotted base plate adapted to be secured to the bed plate of any ordinary sewing machine by means of a thumb. screw 60 11 passing through the slot 10 and threaded into the machine bed plate. 15 is an angle plate pivoted at 16 to base platelO and formed with a downwardly presented integral lug 17, which'in the normal position of 66 the attachment shown in Figs, l, 2' and 3, i engages the front edge of plate 10 to determine the operative position of the device. WVhen the device is thrown into inoperative position as shown in Fig. 4, the lug 17 en- .70 gages a shoulder 1O formed by a slight "cutout in the plate 10. Angle plate 15 has a vertical projecting flange 15 upon which is horizontally pivoted at 20 a supporting plate having an integral limiting lug26, 75 which engages flange 15 when member 25 is raised to its upward limit.

The support 25 has rigidly secured to it and projecting approximately horizontally from it a supporting arm formed pref-- $0 erably of a steel wire or rod, which issuitably bent to provide a tape guiding loop 31 braced by portions 32, 33 and a projection 34 upon which is rigidly mounted the cylindrical shell 35 having diametrically opposite 85 tape receiving slots 36 which extend longitudinal'ly of the cylindrical shell and permit the passage of a tape diametrically through the shell.

40 is an inner guiding and tensioning 9 member of approximately cylindrical shape, having a tape guiding slot cut longitudinally in it so as to extend diametrically through it and a circular guiding head 42 jou-rnalled in the end of the shell 35 and it rear cylindrical portion 43 journalled in the inner-end of shel This member 40 is so mounted that it can be ad- .justedwithin the shell 35 to cause its tape guiding slot 4C1 tore gister' with slots 36lof 50 which is adapted to engage inany of the notches of the toothed segment 47* formed upon the plate 47, whereby the inner member 40 can be secured in the desired adjusted position within the shell 35.

The drawing shows thedevice as it isappliedqto an ordinary sewing machine in which 60 represents a slightly modified presserfoot havinjga needle receiving slot 61 and an inclined tape guiding slot 62. hen the tape guiding and tensioning device is in its operative position as shown in Figs. 1, 2 and 3 of the drawings, it will'be obseryed that a curved finger 55 rigidly attached to shell member 35 engages the up turn'edtoe of the'presser foot 60, so that in the operation or the sewing machine the guiding and tensioning member will vibrate vertically'with the presser foot, the device movingjor this purpose upon the horizontal pivot 20. Thetape to besewed to a piece of wdrlris fed from a spool Or other source through the guideloop 31 and slots 36 and ll-of. the tensioning device andthe slot 62 ofthe presser foot and as it is sewed in place itffe edsflthrough sai dguide. When arrangthe machine for apiece of work, the tape is threaded laterally into the registering slots of shell member 35 and inner member 40 through the open ends of said slots, and likewise into the guiding slot 62 of the raised presser toot;the presser toot being then lowered and the sewing machine operated in the usual way. As the, worlr'starts, the operator adjusts the tension upon the tape to suit-I theparticular work by moving finger lever 50 to throw the guide slot of inner member 40 more or less out of registry with theguidefslots 86 or the shell 85, the result of which operation is indicated in Figs. 7

and 8. lVhen the device is out of use it can be moved to the positionshown in Fig. 4: of thedrawing. i
